The pilot of the F8F shown on its back, failed to heed a previous warning against landing too close to the edge of a runway that had been plowed numerous times during the winter. He allowed his plane to swerve slightly to the right and caught his wheel in the snow-bank while traveling at a speed of about 60 knots. The plane ground-looped, turned over, and slid 15 feet on its back before coming to a stop.
